only the entered data is included in the electronic image (i.e., remove
the form’s lines and boxes).

to eliminate from the front side. Selections are:
None
,
Red
,
Green
or

.

or

.
JPEG Compression
— click
Enabled
to select a JPEG Quality option.
Choices are:
•
Good
: a fair amount of compression but still produces acceptable
image quality.
•
Better
: some compression which produces decent image quality.
•
Best
: minimal compression which produces very good image quality.
•
Custom
: select this option to customize your JPEG compression
values. When selected, the
YUV
and
Value
percent options are
available.
-
YUV
is a type of color space used in JPEG compression. The 4-2-2
selection (default) uses downsampling (throws away a lot of the
image color data) and generates smaller files compared to the 4-4-4
selection, which uses no downsampling (keeps as much image
color data as possible) and generates large files.
-
Value
: a high percentage value compresses the least (and
generates larger files), while a low percentage value compresses
the most, generating smaller files, which can result in lower quality
images.
